"Nana" is a lullaby which was also adapted to flamenco.
Some “nanas” were well received by flamenco singers and are performed with other topics. Original “nana” lyrics were discarded and love songs were chosen instead, keeping primitive melody. Most of time, it is performed, following “soleá por bulerías” rhythm.
Currently, there are two main versions of “nanas” flamencas. Both are inspired by most popular version of "cante para dormir niños" (singing for children to sleep). The first one is attributed to Bernardo el de los Lobitos, and the second to Maria Vargas.
